There is a city where a road service provider (RSP) builds and maintains all roads. At strategic places, there are road checkpoints where the RSP can block traffic.
Recently, there has been a series of bank robberies. The city has strange laws: Bank robberies are illegal in he city, but hard to prosecute directly. The bank, knowing who participated in the robberies, asks the RSP to block the robbers' traffic.
The RSP refuses, bank sues the RSP.
